IMPROVEMET IN STEAM-GENERATORS.

The Schedule referred to inf-these Letters Patent and making part of the same.

projections, for the purpose to be hereinafter set forth; "and also in` arranging the various parts of'-` the generator with relation to each-other as that the full effect ofthe calorie arising-from the combustion of the fuelwill be utilized; and whereby the Afurnace may be more conveniently and effectively replenished with fuel when necessary.

Description of the Accompanying Drawing.

Figure-1 is an elevation.

Figure 2 is a vertical central sectional view -of lig. 1, from vthe top down to the plane of the line :v x, and and elevation of the interior rings and continued vertical section of` the outside jacket from the line x a; to the base." Y v Figure 3 is a horizontal view of fig. l, on the line ill llshown at fig. 2.

General Description.

' projecting from holes pierced in the rings A.

C C are hemispheres with annular flanges, c c, which, :when brought-together, form aspherc.

D is a base, on which the whole device rest-s.

The upper surface ofthe base D carries the firegrate'd, and thelower part is made hollow and serves as an ash-pit, with a door, dcommunicating there with from the outside.

E isa conical-shaped projection upward from the surface of the fire-grate, and being in the center thereof serves to occupy thcplace of fuel, which, without it, would be consumed without its heat reaching the vrings A; and further, it may be .pierced with holes above the combustible matter, for the purpose of' admitting air to aid in consuming -the smoke.

Figure 4 is-a top view of the steam-dome and rings A G isa jacket or casing, a little larger in its interior diameter than the outside diameter of' the ringsl A,

l and has its lower edge or end resting on a flange from the top of the base D, and completely' encreles and i envelopes the rings-A A A A` A.

Aor circular tubes, connected by tubes or :flanged II is a pipe, communicating from the outside of the jacket Gr and with the lower ring A', through which water may be pumped into said ring A' from any suitable reservoir. l

I isa pipe, communicating with the interior of' the sphere C, through which steam may be taken to any desired place.

J is a door in thejacket G.

K K K K are the heads o'f bolts which pass through the flanges c c, the rings A A A A, and flanges B B B B, and the flange on the top ofthe base D, where they are provided with tapsor nuts, lwhich may be tightened up as desired, for the purpose ol' holding the sphere C and rings Ay allv securely in place.

rlhe construction and as follows: y y

Any desired number of the rings A may be' placed operation of my invention are on top of eachother, one of them A being cast with a section left out and the ends closed, as shown -at fig. 2, through which fuel may be inserted, or communication be hadwith the interior for any other purpose.

Any desired number ofthe circular flanges B may be cast .on each ring, (eight are shown in the drawing plaiulyatig. 3,) and by the openings in these flanges each ring communicates with the one adjacent.

Theflanges are milled oli` to form the joints, the rings are then brought together' and secured by means ofthe holt-s which pass through a portion of the openings inside of flanges c c c c, upon which is placed heads or caps K K K K, andnnts K K" lof the sphere extends downward into the interior.

Thebolts which pass through the rings A, for the purpose of binding them together, also pass through th'e flanges c c, and where. they-pass through the lower flange c the opening is enlarged and communicates with the flanges BI B B B on the upper side of the upper rin gA, admitting the steam thereby from the upper ring A to tue sphere O.

It will be plainly. seen from the drawing that the lire being made in theinteriortheheat therefrom may communicate freely with all parts of the surface of each and every ring, and the water being kept up to about the second ring from the top, nearly the entire heat generated may be utilized in heating the Water in; the lower rings, and in superheating the steam in the upper rings and in the sphere or dome C, and a Stop-cock in pipe I will enable the operator to deliver steam superheated and dry in quantities as required, and for any purpose desired.

C Zctims.

I claim as my inventionl. The conical-shaped elevation E on the grate al, when arranged to operate with said grate and rings A, substantially as .described and for the purpose specified.

2. The arrangement of base D, rings A A', and partial ring A, construetedas described, -witlranges B, and united by bolts K, dome O, and casing G, all as and for the purpose substantially as set forth.
